I This invention relates to a push-button multiple switch for lamps.

An object of this inventionv is to provide a push-button multiple switch structure-designed' for table lamps or the like which is so construct` ed and arranged as to provide for breaking the circuit between pairs of contacts, so that where a a push-button multiple switch of this kind in which the operating button is loosely carried by the base and can be rotated in either direction without affecting the switch.

A further object of this invention is to provide a push-button multiple switch structure emo bodying a rotary contact carrier with wipers engaging the carrier, and also embodying an `improved means including a pawl and ratchet for progressively rotating the carrier.

With the above and other objects in view, my

invention consists in the arrangement, combinartion and details of construction disclosed in the drawings and specication, and'then more particularly pointed out in the appended claim.'

In the drawings:

Figure 1 is a plan view partly in section of a push-button multiple switch structure constructed according to an embodiment of this invention.

Figure 2 is a sectional view taken on the line 2-2 oi. Figure 1.

Figure 3 is a sectional view taken on the line 3-3 oi Figure 2.

Figure 4 is a diagrammatic View showing the electric circuits associated with this switch structure.

Referring to the drawing, the numeral Iii designates generally a frame structure which is formed with a pair of upright plates il which are secured together by means of a, connecting bar I2 and fastening members I3. The frame structure I includes a pair of laterally projecting bars i4 secured to the outer sides of the side members II by fastening means i5, and the bars I4 are adapted to be secured by fastening means I 6 passing through the bars i4 to the base I'I of a lamp structure.

In the present instance the push-button multiple switch structure is disposed within the hollow base I'I which includes a top wall I8, a side Wall iV claim. l(o1. o-8S 2l thereof a bridging contact 29.

I9; anda removable bottom wallzZc. A contact carrier generally designated as 2| is rotatably disposed between the side members Ii and comprises a shaft 22r journalled lbetween the side members rII and having fixed thereto a pair of cylindrical insulating members 23 and 24.

A ratchet 25 is disposed between the inner ends of the cylindrical insulating members 23 and 24 and is fixed to the shafty 22'. The insulating kmembers v23 and 24 are formed with circumferentially spaced apart longitudinal grooves 26 and 27, respectively. The insulating member 23 has disposed in one groove 23 thereof a bridging contact 23 and insulating member 24 has disposed in an aligning groove The contact 28 is disposedvadjacent theinner portion of insulating member 23; whereas, Contact 29 is disposed adjacent the outer end portion of insulating member 24.

A second bridging contact Suis disposed in av second'groove 230i insulating member 23 .being positionedl adjacent the outer end portion of member 2'3. An aligning contact 3l is disposed in insulating member 24 adjacent the outer portion of this member. A third bridging contact 32 is disposed in another one of grooves 26 of insulating member 23 adjacent the outer' portion Aof this member, and an associated aligning contact 33 is disposed in another onev of the grooves 2l of insulating member 2li and is adjacent the inner portion of member 2d. An inner pair of wipers 34 and 35 are fixed to an insulating bar 36 which is carried by the connecting bar I2. An intermediate pair oi wipers 3l and 38 are also secured to the insulating bar 36 outwardly from the wipers 33 and 35, respectively, and are adapted to be connected to a source of electric current supply by means of conductors 33 and fill, respectively. An outer pair of wipers 4I and 42 are also iixed to the insulating pair 36 outwardly of the intermediate supply wipers I3l and 38.'

Contact 30 is adapted upon rotation of oarrier 2l to bridge the two wipers 3l and 4I, and at this time contact 3| is in a bridging position across wipers 38 and d2. When carrier 2l is rotated to close a circuit to contacts 23 and 23, contact 28 will bridge wipers 34 and 3l, and contact 23 will bridge wipers 38 and 42. When contacts 32 and 33 are in circuit closing position by rotation of carrier 2l, contact 32 will bridge wipers 3l and 4I, and contact 33 will bridge wipers 35 and 38.

Carrier 2| is rotated by means ofv a pawl 43 3 which is pivotally carried on a reduced intermediate portion 44 of a shaftl 45. The shaft 45 is formed at the ends thereof with reduced dameter studs 46 which slidably engage through horizontally disposed elongated slots or guides 41 which are formed in the sidemembers Il of the frame Il).y A pair of springs 48 are connected at one end thereof to the studs 46 and at the oppositezendstheleof to laterally projecting pins 49 which are carried by the frameiside members '.Ihe springs 48 constantly urge the shaft 45'to move inwardly at which timexthesfpawlz,Alwill idle or ratchet over the ratchet member 25. The

shaft 45 is moved forwardly torotatethecarriei 2| by means of a pair of bellcrank1 1eversf5 which are rockably mounted on a shaft 5Lssecured between the side members l I. The inner arms V52 of the bellcranks 50 project upwardly'and'.y bear against the inner side1 of the shaft 45, and the inner, arms. 52 `are Vdispcsed zonvcppositeides; pf '5, the pawl 43.
